An Adaptive Management Working Group has been established by the Williamson County
Conservation Foundation to review data on a regular basis and make recommendations for
specific changes in management directions related to the Federal standards for Occupied Sites.
The Adaptive Management Working Group duties include, but are not limited to, development
of an annual report regarding the preservation of the Georgetown Salamander, continuous
monitoring of the Georgetown Salamander, assessment of research priorities, adaptive
management of preservation of the Georgetown Salamander and the effectiveness of achieving
the above objectives. The City Manager will appoint two Qijy employees with appropriate
technical expertise in the fields of Planning. and development and system engineering as
members to the Adaptive Management Working Group. The efforts of the Adaptive
Management Working Group will be led by the Williamson County Conservation Foundation
staff.

meters upstream and downstream from the approximate center of the Spring
outlet of an Occupied Site. The Red Zone shall be bounded by the top of the Bank
and shall not extend beyond any existing physical obstructions that prevent the
surface movement of Georgetown salamanders, such as roadways, buildings,
retaining walls, dams, and culverts.

established for the subsurface area that drains to the S-orima or Springs at an
Occupied Site. Except as provided below, the Orange Zone shall consist of that
area within 300 meters of the approximate center of the Spring outlet of an
Occupied Site, except those areas within the Red Zone. The Orange Zone shall
not include pre-existing development or areas without the potential for
containing Georgetown salamander habitat as determined by the Geologic
Assessment based on site specific, hydro -geologic conditions, for instance, where
the Edwards Aquifer is absent.
b. No Regulated Activities may be conducted within the Orange Zone other than:
1. Activities permitted in the Red Zone;
2. Wastewater infrastructure installed roughly parallel to a Stream provided
that such infrastructure is installed on the side of the Stream opposite the
